APPARATUS FOR COVERING CYLINDERS W ITH CARD-FILLETS.

SPEGIFIGATTON forming part of Letters Patent No. 244,568, dated July 19, 188 1. Application filed January 12, 1881. (No model.) Patented in England December .27, 1878.

To all whom "it may concern:

Be it known that I, JOSEPH STANDRING DRONSFIELD, a subject of the Queen of Great Britain and Ireland, and residing at Oldham, county of Lancaster, England, have invented certain Improvements in Apparatus for Govering Cylinders With Card-Fillets, (for whichI have obtained a patent in Great Britain, No.

of which the follow- 1 chase, the fillet becomes tightly and regularly wound upon its surface. v

In the accompanying drawings, Figure 1 represents an end elevation, Fig. 2 a front elevation, Fig. 3 a plan, of the improved apparatus, and Fig. 4 i's'an elevation of the prop for supporting the end of the purchase.

In the drawings, A represents the framing of an ordinary carding-engine, and B the main.

I carding-cylinder ofthe same.

Upon one of the axles of the carding-cylinder a purchase, 0, is loosely mounted. The frame of this purchase consists of two side cheeks, d, which ai-e bolted together at each end. In the cheeks are formed bearings for the axles of spur-gearing. e

A pinion, e, is fixed upon an axle which is provided with a winoh-handle, f. The said pinion gears with a spur-wheel, g, to which is fixed a pinion, h, gearing with a spur-wheel, i. The last-named wheel is secured to the axle of the carding-cylinder by means of set-screws or by other suitable means. When the handle f is turned the cylinder B is caused to rotate.

The outer end of the framed is sustained by means of a leg or'propflc, thelower end of" which rests upon the floor. The prop is made adjustable in .length in the manner indicated in Fig. 4, or in any suitable manner, in order that the apparatus may be made suitable for engines varying in the heightof their cylinderaxles, or that the winch-handle may headjusted at a convenient height for the operator.

Upon the axle of the wheel-g a spur-pinion,

screw-shaft o.

i Z, is fixed, and this pinion gears with a wheel,

m, mounted upon a stud which is secured to the cheek d. The said stud passes through a slot formed in the cheek, and is secured by means of a nut. The distance of the stud from the axle of the wheelg is thus capable of being adjusted, in order that the proportions of the gearing Z and m may be varied.

' To the wheel m is secured a chain-wheel, which is connected by means of a pitch-chain with a wheel, 42, fixed on one end of a screwsh'aft, 0. The screw-shaft is fitted to revolve in hearings in a bed,P, whichis mounted upon the side frames, A, of the engine. The bed P is formed with V-slides andis suitably planed to receive a carriage, It, which is fitted to slide to and fro upon the end. A shaft, 8, is fitted in bearings in the carriage, and upon this shaft is fixed a worm-wheel, t, which gears with the The shafts may be turned by means of a winch-handle, and when so turned the wheel t acts upon the threads of the screw-shaft as upon a spur-rack, and the carriage is moved upon its bed in one direction or the other, as

may be desired. When the carriage is to be actuated by means of the screw-shaft, the shaft .8 is prevented from revolving by tightening a screw-clamp, c, and the screw-shaft then acts upon the worm-wheel t as upon a nut.

In the carriage It acone-pulley, 'w, is arranged to revolve, and to the carriage a shunting-plate, w, is secured. Above the smallest cone of the pulley a trough, y, is'fixed. The trough is, by preference, made to suitthe width of the card-fillet, and it is fitted with a loose plate, which can be lifted out. The card-fillet it passes through the trough with the dents upward, and the plate rests upon. the dents, and by its weight imparts acert'ain amount of tension to the fillet. "A weighted lever, a,

pressing upon the plate, regulates the pressure upo'uthe fillet. The fillet passes from the inner end of thetrough y, and is brought around the small end of the cone-pulley to the shunting-plate. The shunting-plate is formed with guiding surfaces or channels, which are curved and inclined in such a manner as to receive the fillet from one step of the cone-pulley and to deliver it to the next step thereof. The fillet is thus passed from one step or diameter of riage.

the cone to another, until it passes to the cylinder from the shunting-plate through a guide or supporting arm, 2, which is fixed to the car- A portion, 00, of the shunting-plate is secured to the main plate by means of a bolt, and can be adjusted so as to vary the angle of 'delivery of the fillet to the cylinder.

The manner of using the apparatus may be described as follows: The bed P having been mounted upon the framing, and the purchase 0 arranged for action, the fillet is passed through the trough, and around the steps of the cone, and over the guiding-surfaces of the shunting-plate, the end of the fillet being then secured to the card-cylinder. The winch-handle f is now turned, whereby the screw-shaft is rotated by means of the gearing c gl m and the pitch-chain.

It must be understood that the gearing must be so proportioned with relation to the pitch of the screw-shaft 0 as that the carriage It is moved a distance equal or suitable to the width of the card-fillet during each revolution of the carding-cylinder. This being the case, when the h andle f is turned the fillet is drawn through the inlet-trough and over the cone-pulley and shuntingplate, and is coiled upon the cardingcylinder, the carriage It sliding upon its bed as the coiling proceeds, so that the coils are regularly and closely laid upon the cylinder. The fillet is secured to the cylinder in the usual or in a suitable manner.

The cone-pulley w is used in order that the fillet may be coiled upon the cylinder with a suitable amount of tension. In practiceI cover the cone-pulley with leather, in order to increase the frictional resistance to the passage of the fillet. Other materials than leather may be found to answer the purpose.

It will be seen that the surface of the larger end of the cone will travel faster than that of the smaller end. This has the effect of tightenin g the fillet, and the frictional resistance to the passage of the fillet over the pulley and over the shunting-plate, aided by the pressure in the inlet-trougl1,imparts the requisite tension to the fillet. If the tension is not sufficient a suitable brake may be applied to the cone-pulley, or the pressure in the inlet-trough may be increased by the means hereinbefore indicated.

A conical or cylindrical drum may be used in lieu of a stepped cone-as, for example, the fillet may be coiled around a cylindrical drum, which is fitted with a brake which may be adjustable.

Pulleys having their axes arranged diagonallymay be usedin lieu of the aforesaid shunting-plate; but the frictional resistance would be less, and a greater length of fillet would be required to pass through the tension apparatus.

I may dispense with the trough and the pressing-plate therein and substitute therefor any other suitable form of guide for the fillet, or the fillet maybe guided by the hand.

Other modifications may be made in the apparatus without departing from the nature of and intent of my invention-as, for example, a rack and pinion may be substituted for the aforesaid screw-shaft and worm'wheel. In some cases the apparatus may be provided with a suitable framing, so as to form an independent machine, in which a card-cylinder which is to be covered may be mounted.

I claim as my invention 1. The vcombination ot' a cardingengine frame with cone-pulley and shunt plates or pulleys and devices, substantially as described, for imparting to the said cone-pulley and shunt plates or pulleys a traversing motion on said frame.

2. The combination of a' carding engine frame with cone-pulley, shunt plates or pulleys, and inlet-trough 1 having a pressingplate and mechanism, substantially as described, for imparting to said cone-pulley, shunt plates or pulleys, and trough a traversing motion on said frame.

3. The combination of a carding engine frame, having a guide-bed in line with the cylinder, with a traveling carriage provided with tension devices for the card-fillet, and operating mechanism, substantially as described, for the said carriage and the card-cylinder.

4. The combination of a cardingengine frame, having a guide-bed, I, and screw-feed shaft 0, with traveling carriage R, provided with tension devices for the card-fillets, and a worm-wheel, t, and gearing, substantially as set forth, for imparting motion to the said shaft and the card-cylinder.

5. The combination of the frame, guide-bed, and feed-shaft with traveling carriage provided with tension devices for the card-fillets and worm-wheel t, and with the purchase G and its gearing adapted to be applied to the shaft of the card-cylinder, all substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two sub- 1 1o scribing witnesses.
